Friday 7/31/98 8:23 AM John Young I am reading parts of http://www.jya.com/cracking-des.htm#foreword. Bill Goldrick and I talked on the phone several days ago. Goldrick had been reading about Cracking DES at jya.com. Goldrick reminded me that in the late 1980s that NSA employee Mark Unkenholtz told me and others at Sandia that NSA had broken DES. Unkenholtz is the Mark mentioned at http://jya.com/da/whpda.htm Appendix S. Amy Johnston, cc, was Mark Unkenholtzs fiancee. I faxed the Hern DRAFT letter to her for reason that NSA did not have an unclassified fax machine readily available. For those who might want to get Sandia crypto history right "The First Ten Years of Public Key Cryptography," Proceedings of the IEEE, 76(5), May 1988. referenced at http://www.aci.net/kalliste/nukearse.htm, Goldrick 1 was supervisor of Mark Schaefer who build the second CTBT seismic data authenticator http://jya.com/da/whpda.htm I used Schaefers TEMPEST design schematics. 2 supervised deployment of the seismic stations in Hamar Norway. This is detailed in William Burrows book Deep Black. 3 supervised Jim Walkup who was responsible for placing the CTBT data authenticator described at http://jya.com/da/whpda.htm in the field. date: September 11, 1991 to: Bill Payne, 9236 [Signature] from: James Walkup, 9233 subject: DSVS authenticator records 4 handled recall of some CLASSIFIED algorithm eprom chips that somehow made their way into the field in 3. NSA believes that the STEP size and non-linear feedback function are CLASSIFIED SECRET/NSI. http://jya.com/da/whpda.htm The NSA R register feedback function is classified. For each data bit processed, both the F and R registers are stepped multiple times. The number of steps is classified. But we ALL now know the CLASSIFIED SECRET/NSI value is 31. http://jya.com/nsasuit.txt 5 rejected NSA employee Donald Simards http://jya.com/nsasuit.txt order to deploy the classified algorithm. Simard told Goldrick that NSA would DECLASSIFY Benincasa's algorithm LATER. Lets all hope for settlement of the unfortunate matter before it gets WORSE. I want to revise my book http://www.apcatalog.com/cgi-bin/AP?ISBN=0125475705&LOCATION=US&FORM=FORM2 It has been over about 27 years since I directed any Ph.D. students http://www-hto.usc.edu/software/seqaln/doc/html/gfsr.3.html http://www.friction-free-economy.com/ http://www.mhpcc.edu/general/john.html Perhaps I should get back into the business of directing and participating in Ph.D thesis work? I have some GREAT Ph.D. thesis topic ideas in the area of FORTH is applicable to hardware intensive projects implemented by one, two, or three workers. Robots, computer numerical controlled machines, weapons programmers, cryptographic processors, engine controllers, unmanned observatories, computer hardware debuggers, laser printer graphics controllers, video games, work station device drivers, writing BASICs are all candidates for FORTH software technology. FORTH is a one of the top choices for embedded controller applications. Later bill
